FORv THBE SHING-MACHINES.

Patented Oct. 20, 1908., l

To all who/m 'it may concern:

Be it known that I, CORY W. SELLERS, a citizen of the United States, residing at Be loit, in the county of Mitchell and State of Kansas, have invented a Pneumatic Feeder for Threshing-lvlachines, of which the fol- .and a fan, or itspeqiivalent, for creating a blast through said tube.

. Another feature vof the invention residesv in a head adjustably secured to the forward end of the tube so that it may accommodate itself to the upper-,surface ofth'e stack.

, A further feature consists of a feeder arranged at the mouth of the tube for loosening the kgrain in the stack, severing the cords when it is bound in bundles and uniformly feeding the gra-in to the tube.

Anotherfeature consists in rigging for adjusting the tube in a vertical plane s'o that the latter may be raised or lowered as desiret.

A further feature consists of means for swinging the tube in a horizontal plane so -that its Vfeed end maybe made to oscillate over the stack and thus take the grain from the latter in a uniform manner.

Another feature ofthe invention resides in Ameans for extending and teleseoping the tube so that it may be'adjusted to Vthe desired point.

As the construction and arrangement of the above-mentioned features may be modified I do not limit myself to the construew tion shown and hereinafter described.'

@ther features of the invention will hereinafter appear. and in order that said invention may be fully understood reference will now be made to the accompanying` drawings. in which:

Figure 1 shows a broken side elevation of the feeder applied to the forward end of a tlmeshing-machine, the latter being in vertical'section. Fig. 2 is a horizontal section of same on an irregular plane drawn through the axis of the fan. Fig. i is an .inverted'plan view of a turn-table'and its op- 4to a pneumatic y erating mechanism all of which form a part of the invention. Fig. L)ris a vertical section ofI samel taken on line `IV-IV of Fig. 3. Fig. 5 is a broken side elevation of a suctiontube and a portion of the mechanism for 0perating same. Fig. 6 is a transverse section taken on line VIe-VI of Fig. 5 with the rear porti-on of the suction-tube in dotted lines.

Fig. 7 is a broken side elevation of the front portion of the suctiontube.l Fig. 8 is a ver-4 tical section of same showingthe feeding mechanism carried thereby. Fig. 9 is an in verted plan view ofthe same. Fig. 10 isa broken plan'view ofthe forward portion of the suction tube. Fig. 11 is a transverse seci tion of same taken' on line XI-XI of Fig. 10. Fig. 12 is a transverse sectiontaken on line XII-XII of Fig. 10. Fig. 13 is a front elevation of a frame for supporting the forward portion of the suctionftube when the latter is at rest and for supporting t-he case of a suction-fan employed in carrying out the invention. Fig. 14 is-a` transverse section of a portion ofthe gearing for reversing the motion of theturn-table. Fig.

15 is a broken. inverted plan view 'of the shifting-lever employed in reversing the motion of said turn-tahle.

In said drawings, l designates .the forward portion of a threshing-machine pro- Videdwith the customary cylinder 2 and concave 3. Cylinder 2 is mounted upon a transverse shaft 4 journaled in bearings 5 and provided at one end with two fixed pulleys 6 and p 9 designates an irregular shaped frame carried by a pair of sills 10 projecting from the upper forward portion of the threshing machine and having their forward ends supported by braces 11.

12 lesignates a case secured to framel 9 and inclosing a suction-fan13 mounted at one end upon a stub-shaft 14 journaled in al bearing 15 secured to one side of frame 9.

8 designates a pulley fixed to the outer end' 100 of shaft 14C and driven by pulley 7 through the linstrumentality of an endless belt 8a.

'The inlet end of case 12 is provided with a iange 16 secured to' the adjacent sidei ofV frame 9 for the reception of one end "of an 'elbow 17 forming part of the rear section of suction tube 18 provided at its opposite end with an upturnedl elbow 19 provided with an.

The discharge opening of case 12 communicates with a discharge ipe 24 communicating at its discharge en with the forward portion 4of the threshin -machine Pipe'24 1s curved as shown in ig. 1, and rovided grate 25vwhich con ucts the grain to the cyl1nder. The bars forming grate 25 are placed close together to prevent the grain from passing therethrough, but a]- low a portion of the blast from fan 13 to ass therethrough and enter anopening 26 ocated in front of the rain will-not be blown over the cylinder an' grain in the ain-pan will be agitated and cllleansetll of c ali' by the air blowing theret rou y 27 esignates a vertical section of the suction-tube provided at its lower terminal with an annular shoulder 28 abutting against shoulder 20 and svc'iveledv in the uper portion of socket 21 so that saidsection 27 may rotate on its vertical axis.l The remainder of the suction-tube consists of a flexible elbow 29 communicating with the upper terminal of section 27 a section 30 communicating at its rear terminal with' the upper portion of elbow 29, a section 31 telescopically arranged in .section 30, a flexible joint 32 communicating with the forward end of section 31, and an enlar ed head 33 communicating with the front end of joint 32 and having a mouth 34 at its underside to receive the grain.

Grain is fed from the stack into mouth 34 by means of a plurality of rakes and bandcutters the forrY-er of which consist of teeth 35 dependingniom bars 36 loosely mounted at their opposite ends upon multi-crankshafts 37 38. Teeth 35 are inclined rearwardly so that they will pick up grain from the upper portion of' the stack and carry it backwardly into mouth 34 so that the suction created by fan 13 will draw the grain backwardly through' the suction-tube, force it into pipe 24 and discharge it at the clyindcr. It' the grain be in bundles the cords binding the latter will be severed by blades 3.9 which also assist the rakes in scattering and feeding the grain in a uniform manner to mouth 34.,` Blades 39l depend from bars 40 loosely secured at their opposite ends to the shafts 37 38 the cranks of which are arranged so that a portion of the rakcs and blades will always be in contact with the grain.

The ends of shafts 37 and 38 extend through the opposite sides of head 33 und are journaled in a casting .4l consisting of' two side-members 42 pivoted at their rear ends to a collar 43 and united at their -forward ends with a transverse portion 44 embracing the lower front portion of head 35% in order to reinforce und protect thc latter ain-pan, not shown.` By thus dividingv the b ast the the threshed from injury. turned extensions 45 provided with oyes tti and forming bearings for a transverse shaft. 47 journaled therein. Shaft 47 is driven hy a bevel-gearwheel 43 and provided at. its opposite ends with a pair of fixed sprocketwheels 49 for imparting` motion through the Side portions i2 have up-V instrumentality of endless sprocket-chains .p01 'on of cable 52 has two strands 54 attached at their diverging ends to eyes 46 in order to balance head 33. Cable 52 passes upwardly and rearwardlyover a guide-pdf ley 55 carried at the upp'er end of a tower 56, and' the lower rear end of said cable l is attached to drum 53 as above described. 4Said drum is rotated to either wind or unwind the cable by means of a worm-wheel 57, a worm 58 meshing therewith, and a hand-wheel 59. Worm -4 wheel -57 is fixed upon the drum-shaft 60 jonrnaled in hearings 61 secured to a bracket G2 secured to the rear side of the tower; Worm 5S and hamlwheel 59 are fixed upon a shaft (i3 journaled in bearings (A secured to bracket (S2 Head 33 is adjusted vertically from joint 32 'independently of' the suction-tube so that its mouth 34 and the feedingl mechanism carried thereby may always be retained in proper relation to the upper surface of the stack. 'lhis adjustment is obtained by seltloeking mechanism consistingofa segmental rack 65 secured to side-members 42 and interineshing with a worm (iti, fixed upon the forward end of ay shaft 67 telescopieally arranged in a tubular shaft (53 secured at itsrear end b v means oi a universal joint (if) to a shorty shaft-section 7 t) telescopically arranged in a tubular shaft 71 secured by a universal joint 72 to ashort shaft sect-ion 73 provided at its'rear end with a handwheel 74.

` Section. 31 is adjusted longitudinally in section 30 by `a pair of arms 109 extending rearwardly from the opposite sides of collar 43 and through a) pair. of stops 110 secured to-the'oppositesides ofthe front portion ofsection 30. The Vopposite sides of said section4 are' priovided with clips 111 arranged in longitudinal alinenient so that arms 109 mayl pass .therethrough when adjustedlongitudinally, the rear.- ends of saidv arms being pointed as indicated ,aty 112 so that they will` readily pass backwardly between the clips which-1 have spaces 113 for. the passage ofsheave-wheels 1114` journa-ledin the rearfportions of said arms.

Cog-wheel U6 is provided at its underside with an annular `roove 133 for the reception ol an annular bearing 134 upon which said cog-wheel is journaled. Bearingr 134 is supported by three arms 135 arranged vcrticall'y above arms 22 and secured to the upper portion of socket. 2X1.

That portion of the suction-tube consisting of scctions27, and 31 are swung,` in

a horizontal plane, turning at the joint l'orn'ied between socket Q1. and shoulder 28, by mechanism consistingI of an annular turntable 136 loosely embracing cog-'wheel96 and provided at its periphery with cogteeth 137 which mesh with and are driven by a worm 138 fixed upon a transverse shaft 139 jonrnaled in bearings 140 depending,r trom the umlerside of plate 23.

'lurn-table 136 is provided at its upper and lower surfaces with annular tracks 141 142, respectively, and is held in a horizontal plane by conical 1ollers143 engaging said tracks and mounted upon shafts 144, journaled in hearings 145 secured to the upper A and lower surfaces ot' plate 23 having a eentrally disposed annular opening 116 for the reception of the turn-table, which latter carries the tower (see Fig. 4)." The lower corner posts ot' the tower overlap cog-wheel 116 and thus prevent the latter from moving upwardly, there being lm sliqht space, however, between the upper sul-tace of said cog t wheel and the lower` portion of the posts to prevent the former-from rubbinghgainst the latter and thus creating friction. Turntable 136 is providedat its underside with an annular Iegroove 147 torthereeeption of lhe upturncd portions of brackets 148 which prevent said turn-table from shitting longitudinally and thus causing undue friction between its inner surface and the periphery oi cog-wheel 96. The turn-table is also provided with an annular series ot' holes 149 l'or the reception of two pins 150 151 projectinplr upwardly so that they will contact with`the rear terminal ot a shittingr lever 152 arranged in the path thereof and adapted to be thrown in opposite directions by said pins. Lever 152 is tulerumed upon a pin '153 projecting upwardly .from a fixed cam 151 havin;lr two notches 155 which are alternately engaged by a dctcnt 156 as the levee is shifted back and forth.

'y Detent 156 is slida'bly arran, ,1fed in ears 157 inthe underside ot' the lever and provided with a tixed collar 158 against which one end ot' an evi ansion-spring` 159 abuts in order to hohl the forward terminal of said,

detent in engagement with the cam. W'ith this arraluuuncut the lever is reliably held in either ot' its positions until shifted by the pins.

The rear end of lever 152 has a forked dependingmember 16() provided with pins '161 engagingy the opposite sides of a peripheral groove, 162, centrally-disposed'.in a clutch 163 provided at its ends with oppositel disposed teeth 164 adapted to alternately engage similar teeth 165 integral with the hubs of bevel gears 166 167 loosely mounted upon shaft 139.

Clutch 163 is slidably mounted upon shaft 4 13S) but is caused to turn therewith by a feather 168, fitting into its longitudinal groove 169. so that,\vhen said clutch is alter-4 nately shifted by lever 162 into engagement with bevel-gears 16 167 it will lock them upon shat't 139 and thus'canse them to alternately rotate shaft 135) in ,reverse directions. With this arrangement it is obvious that when one-of the bevel-gears is rotating tlie turn-table in one direction. through the instrumentality ot worms 138. said turn table will continuel in said direction until one of the pins, sav tor instance, 15() contacts with the tree end ol the lever 152 and causes said'.

lever `to shift the clutch into eiwagement with the other bevel-gear, when die latter will immediately reverse the movement of worm 138 and the turn-table until pin 151 contacts with the' shifting lever and causes it to draw the clutch into engagement with the first-mentioned bevel-gear. Thus the turntable,l together with the tower andthe laviveled portion of the suction-tube will be caused to oscillate and swing the feed end of said suction-tube back and forth over the `1ark, the length of the sweepl being determined by thedisposition of pins 150 151. 'For instance, when the lpins are disposed, as shown in Fig. 2. the sweep will be comparatively short'. but when'pin 151 is placed in hole 119 the length of the sweep will be increased to almost a com lete circle. B v removing one or both pins th) parts carried thereby may be rotated a complete revolution.

Bevel. gears 166 167 are driven in reverse directions by an intermeshing bevel-gezin..

wheel 170. fixed upon the upper end ot the inclined shaft 1.71, journaled'in bearings 172 and driven by a. worm-,wheel A173 loosely mounted upon its lower terminaland -provided with a'clutch-member 173" normallye turn-table and it to rest in 'the concave portion-of. freine-9),

means of a'hand-Wheel 179 iXed upon one end of shaft 139, j 180 designates the discharge end: of a tailmg-spout 'communicating withv the suctiontube near its entrance to the tan case so that the fan will draw the tailings through the,

spout and return them to the cylinder through the discharge pipe.

From the above description it is obviousthat I have provided a pneumatic feeder ulnch may be adjusted vertically so that its inlet end may be elevated to the top of' the stack and gradually lowered as the grain taken from the latter, which may be oscillated ina horizontal plane so 'that it Will a threshingmachine,

machine, means sweep back and forth over the upper vsurface .of the stack andy thus take the grain evenly therefrom, and which may be extended or contracted as desired.

Vilhile have shown the fan communicating With the rear portion of the suction-tube it could be-located at the forward end of the latter and thus force the grain through said tube, but l lindby practice that itis desirable to locate the same upon the threshingmachinc and thus relieve the forward end ot the tube of all unnecessary weight. The action of the fan is also more effective when sucking the grain through the tube than when forcing it therethrough.

Having thus described my invention, what I claim and desire to secure by Letters-Patent, is
